I spent hundreds of hours in the game, if not thousands, over the decades. Your best pick would probably be gmdx as it fixes many bugs and annoyances of the original, improves graphics a lot, while staying very close to it.

Revision is popular and cute, but changes too much. Level design on some levels is so different that you can't recognize them, I still get lost despite playing though it at least ten times, as original levels are burned in my memory.

Although this can be changed in settings, I'd still avoid Revision unless you want to have another go at it after finishing the original.
